Abstract

Ce climatiseur comprend des sorties (15, 19) sélectionnées par des portes (11-40) de sélection de mode, disposées à des hauteurs sensiblement identiques sur la face de l'enveloppe du module situé le plus en aval. De manière plus spécifique, l'enveloppe du module présente sur sa face arrière une partie verticale (2a) s'étendant sur le haut en aval des moyens de régulation de température, et une partie horizontale (2b) s'étendant horizontalement sur la face située le plus en aval, donnant à l'ensemble la forme d'un T, les sorties (15-19) étant installées sur la partie (2b) horizontale. La hauteur sensiblement identique des sorties (15-19) permet de réduire la hauteur de la partie arrière du logement unitaire. Ce climatiseur de véhicule comprenant une partie verticale à l'arrière de son enveloppe et des sorties ouvertes sélectivement au moyen de portes de sélection de mode sur la face située le plus en aval de la partie verticale, peut disposer d'un espace suffisant derrière la face supérieure de la partie arrière d'un logement unitaire.
